DeviceNet Object
(Class ID 03
H
)
The DeviceNet Object is used to provide the configuration and status of a
physical attachment to DeviceNet.
Class Attributes
Instance Attributes
1 Setting the MAC ID causes the device to reset automatically, after which it will go online with the new MAC
ID.
2 The Baud Rate setting can not be set while Autobaud Disable is equal to 0. Applying the Baud Rate does not
occur until the Reset service to the Identity Object.
The MAC ID, Baud Rate, and Autobaud Disable settings are stored in
non-volatile memory so they do not reset to the default with each power cycle.
The Baud Rate attribute supports the following settings:
• 0 = 125 kbps
• 1 = 250 kbps
• 2 = 500 kbps
The Baud Rate setting is used only when automatic baud rate detection is
disabled (Autobaud Disable = 1). When Autobaud Disable is set to zero (0),
the module ignores its Baud Rate setting and performs automatic baud rate
